Timelapse Shows Solar Activity Responsible for Recent Aurora Borealis

Footage released by the National Oceanic and Atmospheric Administration (NOAA) shows a solar filament eruption “rippling off the face of the sun” on September 16, a phenomenon that caused aurora borealis to appear in the northern US sky days later.

This video is a 24-hour timelapse caught by the Solar Ultraviolet Imager (SUVI) onboard NOAA’s GOES East satellite, showing a solar filament eruption on September 16.

The eruption of a solar filament can propel a plasma eruption known as a coronal mass ejection (CME) toward Earth, disturbing our magnetic field and triggering geomagnetic storms, which create the auroras in the sky, according to the NOAA.

Residents of North Dakota reported colorful skies overnight September 18 into September 19 as the effects of the CME reached Earth. Credit: NOAA via Storyful
